Screen device

摘要

The present invention relates to a screen device, in which the screen (1) is tensioned in the roll-up and roll-down direction using a tensioning system comprising a tension strip (3) or tension rope or tension cable which is less susceptible to wear and comes off the fastening element on which it is arranged less easily due to the fact that the screen device is provided with one or more lath guide elements (5) which are provided in the longitudinal direction so as to be displaceable with respect to the bottom lath (2) and with a guide element of the tensioning system (8) which is provided in the longitudinal direction so as to be displaceable with respect to the bottom lath (2) by means of one or more ball bearing bushes (9), which are arranged in lath guides (4) and guides of the tensioning system (7), respectively, in order to guide the bottom lath (2) and to guide the tension strip (3) or tension rope or tension cable during the roll-up and roll-down movement of the screen (1).
